The embodiment disclosed herein includes a sheet metal stamping presenting an elongate relatively narrow base section and laterally yieldable converging panel engaging wing members extending from opposite longitudinal margins of said base section.

7 Claims, 8 Drawing Figures PANEL FASTENER CLIP SUMMARY OF THE INVENTION It is an object of the present invention to provide a novel and very practical spring type clip adapted to support panel members in a vertical position. Panels in the form of perforated sheets commonly referred to as pegboard sheets, are often employed to provide partitions in display cases and the like. The present invention contemplates a spring clip of improved and simple construction which particularly lends itself for use with such perforated panel stock.

More specifically, the present invention contemplates a fastener clip of the type referred to above which may be produced in the form of a sheet metal stamping of minimum size which may be initially associated with a panel margin without the potential hazard of structurally impairing or defacing the panel margin during such association. To this end the present invention contemplates a U-shape type spring panel clip having oppositely disposed openings uniquely shaped to facilitate initial association of a panel margin with the clip.

It is a further object of the present invention to provide a spring fastener clip as set forth above having a novel arrangement of panel attachment means particularly applicable to perforated or pegboard stock.

The present invention also contemplates a spring clip fastener for panel margins which may not only require a minimum amount of sheet metal stock, but which also may be produced by the practice of conventional stamping and forming methods, thus reducing the cost of manufacture to a minimum.

' BRIEF DESCRIPTION OF THE DRAWING The foregoing and other objects and advantages will be more apparent from the following detailed description when considered in connection with the accompanying drawing wherein:

FIG. 1 is a perspective view of a display case equipped with panel engaging spring clips of the type contemplated by the present invention;

FIG. 2 is a' perspective view showing one of the partitions detached from the display case of FIG. 1, more clearly to illustrate the manner in which the spring clips may be associated with the panel margins;

FIG. 3 is an enlarged fragmentary sectional view taken substantially along the line 3-3 of FIG. 1;

FIG. 4 is a top end view of the clip detached from the panel member;

FIG. 5 is a perspective view of the detached clip; FIG. 6 is an elevation of the clip as seen from the left of FIG.

FIG. 7 is a fragmentary perspective view disclosing the manner in which a panel margin may be initially associated with the U-shaped spring clip; and,

FIG. 8 is a fragmentary end view seen from the right of FIG. 3, disclosing the slightly arcuately formed prongs or tongs interlocked with the perforated panel.

Referring now to the drawing more in detail wherein like numerals have been employed to designate similar parts throughout the various figures, it will be seen that one embodiment of a panel accommodating spring clip is designated generally by the numeral 10. The spring clip 10 is in the form of a sheet metal stamping including an elongate relatively narrow base section 12. A pair of converging wing members 14 extend from opposite longitudinal margins of the base section 12. Vertically spaced panel attachment members or prongs 16 are struck from the base section 12, in a direction opposite to the wing members 14. The spacing of the prongs or tongues 16 is such that they will register with complementary, similarly spaced apertures or perforations 18 of a partitioned display .case designated generally by the numeral 20. A panel section of the display device 20 is designated in FIGS. 1 and 2,. by the numeral 20a.

Perforated board of the type illustrated herein is readily available, and the spacing of the apertures in the board material standardized. The spring clip of the present invention has a very practical application to board material of this type. The prongs or tongues 16 are spaced so as to accommodate a pair of board apertures as clearly shown in the drawing. Attention isdirected to the fact that it is preferable to form the prongs 16 so that they are generally arcuate in cross section as is clearly illustrated in FIG. 8. The prongs 16 thus provide pairs of work-engaging edges facing each other which are adapted to impinge the edges of the panel defining the complementary apertures 18. The embodiment of the prongs shown by solid lines in the drawing, as for example in FIG. 3, have an approximate length, corresponding with the thickness of the wall or partition of the display case 20. In instances where necessary, these prongs may be longer and bent laterally against the outer surface of the wall as shown by the dotted lines in FIG. 3.

In the preferred embodiment of the clip the distance between the inner surfaces of the wing members 14 in the vicinity of the base 12, is substantially equal to, or slightly larger than, the thickness of the workpiece or panel 20a. Thus as illustrated in FIG. 3, the initial association of the comer of the panel 20a, is greatly facilitated by having the converging wing members 14 formed with arcuate or curved outer edges. Thus the outer edges of the Wings 14, from a point intermediate the opposite extremities thereof, progressively diminishes in distance from the base 12, as said edges approach the complementary extremity of the base. In this manner the presence of the sharp comers is eliminated, and the potential danger of marring or impairing the surface of the workpiece, or panel, is reduced to a minimum. The arcuate contour of the outer edges of the converging wing members 14 serves to guide the panel into association with the clip and thus greatly facilitate the ease with which such assembly may be accomplished. As the wings 14 are forced apart, they ultimately impinge the entire inner surfaces of the wings.

From the foregoing it will be apparent that the present invention contemplates a spring clip device of extremely simple, yet practical form. The curved contour of the wing edges not only facilitate initial association of a panel with a clip as previously described, but also make it possible to produce the clip from a minimum amount of metal stock without sacrificing gripping effectiveness. In many instances the prongs may be used without folding the projecting portions thereof over the panel stock because of the firm impingement of the arcuately disposed prongs with the apertured panel stock.
